SECTIONAL FEED-ROLL FOR GANG-EDGERS.

SPECIFICATION forming part of Letters Patent No. 606,886, dated July 5,1898. Application fileaJuly 31, 1837- Serial No. 646,583. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. BUEK, a citizen of the United States,residing at Richmond, in the county of Henrico and State of Virginia,have invented a certain new and useful Improvement in SectionalFeed-Rolls for Gang-Edgers, of which the following is a full, clear, andexact description.

This invention relates more especially to feed-rolls for that class ofsawing-machines known as gang-edgers. It is a fact that the greater partof the sawing is done to one side of the machine and to such extent thatone end of the feed-roll is worn more rapidly than the other, and henceit results that the feed-roll has to be replaced as a whole when it isonly worn out in part. In some cases the feed-roll is taken out and hasto be sent to a distance for repair, and meanwhile, unless a duplicateis at hand, the machine is idle. Not only so, but freight or expresscharges are high, owing to the weight of the feed-roll. \Vith thesedifficulties in mind I have invented a feed-roll made in sections andwith the sections interchangeable, so that when one section becomes wornit may be replaced by another section of the same roll or by a changesection or by turning the section end for end, or the worn section maybe removed and repaired while the remaining sections are in use. By thisconstruction the machine never need be idle. Moreover, by making theroll in sections the worn section may be removed and returned to themanufacturer for repair, and being separate from the shaft and ofproportionately light weight the transportation charges are materiallyreduced. Anotheradvantage obtained by my invention is that feed-rolls ofdifferent lengths and having the active feeding devices located in anydesired manner may be readily assembled upon a shaft which may be fittedto Work in any machine, and hence my invention is applicable not only tonew machines, but to those already in use.

As already sufficiently indicated, my invention consists of a feed-rollhaving serrated active edges and made up in sections, which sections areapplicable to a shaft or spindle in any desired number and manner, allsubstantially as I will proceed now more particularly to set forth andfinally claim.

In the accompanying drawings, illustrating my invention, in the severalviews of which like parts are similarly designated, Figure 1 is alongitudinal section of one of my feedroll sections in process ofconstruction. Fig. 2 is an elevation. Fig. 3 is a cross-section taken inthe plane of line 3 3, Fig. 2, showing the addition of the blade-holdingmetal. Fig.

The several sections of my feed-roll may be constructed as follows: Aspool a, having undercut or otherheads b, in one of which openings 1)are'made, is taken, and between the heads are arranged the plates '0, ofsteel and having serrated edges. spaced equidistant by means of stripsof wood or other material d, after which all are bound together by Wireor other bands d. The plates may be provided with holes or openings ornotches, as c. orother fusible metal, is then poured through openings 1)until the spaces between the plates are filled up to the level of theinner edges of the strips cl, the metal flowing through the opening 0,and thus keyingin the plates. 85

After the molten metal is cooled the strips d are removed and thesurplus metal trimmed off. The plates are thus rigidly and readilysecured to the spool. So far as the method of and means for securing theplates to the 0 spool are concerned the foregoing description states theinvention of Patent No. 325,339, dated September 1, 1885.

The plates are arranged with their teeth in alinement, so that the saidteeth may be 5 leaving the board as the next adjacent plate :00

Fig. 7 is 6-5 These plates are Molten metal, such as Babbitt 8o in thedirection of rotation touches the board, and by so arranging the platesthe board is fed regularly and straight,- and the impact of the rollthereupon is insufficient to disfigure materially the surface of theboard.

In order to economize in the manufacture of the shaft or spindle uponwhich the sections of my feed-roll are mounted, I use a metallic rod 6of uniform diameter throughout and without reduced ends for the bearingsand for the driving-pulley. The end 6 for the driving-pulley may have akey-seat (2 That end also is provided with a bearingcollar f, which maybe shrunk on it, as in Fig. 6, or such bearing-collar may be movable andsecured by a set-screw, as in Fig. 7, f being the collar and f theset-screw.

If a roll of the extreme width of the machine be desired, thebearing-collar may be used as the abutment for the end section, and thensection after section is applied to the shaft or spindle, and the endsection at the opposite end is secured by a collar or nut g, having aninternal screw-thread, which is adapted to engage a split screw-seat 7L,which is countersunk in the shaft or spindle c, the said countersinkbeing the only reduced portion of the shaft or spindle. As shown inFigs. land 5, the split seatis made up of semicircular halves abuttedagainst one another at one side and against a centering-pin t' at theother side. \Vhen all the sections are on the shaft or spindle and thesplit seat in place, the collar or nut g is turned up against the endsec tion, and the several sections are thus held in place by friction.The collar or nut g, having its screw-thread running in an oppositedirection to the direction of rotation of the roll, serves as a jam-nut,the hold of which is tightened under resistance in operation of theroll.

The sections may be made of any desired length, and sections ofdifferent lengths may be placed upon one and the same spindle or shaft.If it be desired to have only one end or less than the Whole length of ashaft or spindle of given length supplied with my sections,then anabutment-collar 76 may be placed upon the shaft at the desired point,either by shrinking or by a set-screw, and then the desired number ofsections applied to the shaft or spindle and secured by a screw-collaror nut g,such as shown in Fig.4. Furthermore, when it is desired toarrange the active portion of the feed-roll (my toothed sections) atpoints between the ends, asin Fig. 8, dummy sections Z of reduceddiameter, such as pieces of ordinary tubing, may be placed between thetoothed sections and the collars. Thus it will be seen that by makingthe feed-roll in sections in accordance with my invention I am enabledto fill orders in accordance with the individual purchasers wisheswithout the necessity of altering the main construction of the sectionsand their shaft or spindle. Not

only so, but all of the advantages of repair and change andtransportation heretofore referred to accrue.

lVhile I have specially designed my invention for use in gang-edgers, IWish to be understood as not limiting my invention to a feed-roll ofthat one particular kind or class of machine.

Not only may the sections be changed from one end of the shaft orspindle to the other, but the individual sections may be turned end forend when one end is worn more than the other.

Abundant practical tests show that with the use of my feed-roll, and bychanging the sections as they are Worn so as to preserve uniformdiameter of such roll, there is practically little or no output ofcrooked lumber or lumber having its edge out in other than straightlines. Another attribute of my feedroll is that it does not follow thegrain of the lumber.

Of course I do not limit my invention to the means for securing thesections to the shaft or spindle, nor to the described means forsecuring the several collars to said shaft or spindle.

hat I claim is- 1. As an improved article of manufacture, a sectionalfeed-roll for gang-edgers, comprising a shaft or spindle, abearing-collar fixed thereon, a series of change sections arranged onthe shaft or spindle and having blades arranged in longitudinal parallelrows, the said sections being adapted to be changed end for end andrearranged at pleasure upon the shaft or spindle, a screw-threaded seaton said shaft or spindle at the end opposite the bearing-collar, and anut on said seat adapted to be crowded against the near section and topress the sections together and against the collar and frictionally holdthem on said shaft or spindle to turn with it, substantially asdescribed.

2. A sectional feed-roll, comprising a shaft or spindle, a series ofroll-sections mounted upon said shaft or spindle, anexternallyscreW-threaded split seat countersunk in said shaft orspindle, and a nut applied to the shaft or spindle on such split seatand abutted against the endmost section, substantially as described.

3. A sectional feed-roll, comprising a shaft or spindle of uniformdiameter, a series of roll-sections mounted upon said shaft or spindle,'an externally-screw-threaded split seat countersunk in said shaft orspindle, and a nut applied to the shaft or spindle on such split'seatand abutted against the end most section, substantially as described.

In testimony whereof I have hereunto set my hand this 30th day of July,A. D. 1807.

CHARLES E. BUEK.
